How to test your Structured Data

You can load markup into the tool either directly or by supplying a URL. The editing environment for the tool provides these utilities to simplify markup testing:

Automatic highlighting
—once you load your
content in the editor, you can click on a validated field on the right of
the editor to see which line in your markup produced that field. This is
handy for isolating syntax errors.

Search & replace keyboard
shortcuts
—supports plain text and JavaScript
regular expressions. The search and replace status line appears at
the top of the Editor Panel.
